FINRA is issuing this Notice to announce that FINRA is extending by an additional year, until March 25, 2020, the effective date of the margin requirements that otherwise would have become effective on March 25, 2019.

As we explained in a January 29th post, the purpose of this delay is to allow FINRA to consider whether any revisions to the TBA margin requirements are appropriate. According to Regulatory Notice 19-05,

FINRA’s consideration of potential revisions is ongoing.

In other words, the text of the revisions (if any) will be published in the future.
